Why Ammonium Sulfate?
Ammonium sulfate provides readily available crop nutrients.
On field after field, Sulf-N® ammonium sulfate fertilizers have proven to be an excellent source of the readily-available sulfate sulfur and ammonium nitrogen crops crave. Unlike elemental sulfur, the sulfate sulfur in Sulf-N® is readily available to crop roots, providing them with access to the essential nutrients they need upon application. The ammonium nitrogen in Sulf-N ® is also immediately available for root uptake, and resists nitrogen losses from leaching, volatilization and denitrification.
Why should you consider Sulf-N® ammonium sulfate your preferred S source?
The sulfate form of sulfur found in Sulf-N® ammonium sulfate is immediately available for plant uptake. The elemental form of sulfur can take months before it becomes available for use by plants.
FLEXIBILITY OF APPLICATION TYPE AND TIMING
Because it provides nutrients that are immediately available for uptake by the plant, Sulf-N® ammonium sulfate can work in early or mid-season fertilizer blends for crops such as corn and cotton. Research has also shown a benefit of a fall Sulf-N® ammonium sulfate application for winter wheat and continuous corn fields. Sulf-N® ammonium sulfate can be applied on soybeans any time between pre-plant and V4/V5 stages at rates between 75-120 pounds per acre to boost early growth and nodulation. Across crops, Sulf-N® ammonium sulfate can provide the nitrogen and sulfur that crops need when they need it.
Sulf-N® ammonium sulfate has worked consistently for farmers and agronomists, season after season. It’s proven and reliable crop nutrition in a safe, easy to apply form. For decades, AdvanSix has sponsored university research to learn more about the benefits of Sulf-N® ammonium sulfate across a wide variety of crops and growing conditions. There’s a reason why almost every retailer carries Sulf-N® ammonium sulfate: it routinely delivers a return on your investment.
AVAILABILITY OF THE NUTRIENTS YOU NEED
By offering both ammonium nitrogen and sulfate sulfur in one granule, Sulf-N® ammonium sulfate promptly delivers a key nutritional pair essential for plant development. And because Sulf-N® ammonium sulfate granules may be applied on the surface without incorporation, farmers can time applications around weather events, giving them flexibility to ensure these nutrients are sufficient when the plant needs them.
ALWAYS IN STOCK
Sulf-N® ammonium sulfate is widely stocked by retailers because it is a proven, versatile fertilizer for high yielding crop systems. Whether it is used for fall, spring, or mid-season application, Sulf-N® ammonium sulfate is available for farmers to help ensure their crops have the nutrition they need to maximize their yield potential.
Granular Ammonium Sulfate vs. Granular Elemental Sulfur
What is Ammonium Sulfate? (AMS)
A fertilizer containing 21% ammonium-N and 24% sulfate-S
- Readily plant-available S
- May be used to correct in-season S deficiencies
What is Elemental Sulfur? (S)
- Not available unless ES is oxidized to SO4-S, disintegrated ES particles are clustered without dispersion, impeding initial ES oxidation
- Once the particles get to oxidize they become available
